I just received your Larson scanner for my Foam Cylon helmet today … I have since this video diffused the light inside the clear conduit pipe the LEDS are held inside of to make the LED effect a bit more smoother.
He has been posting updates of the costume on facebook.
Craig shared this project which evolved with the assistance of the Octolively project.
Thanks for the previous help you gave me when I was designing my own IR proximity boards. I thought you may want to have a look at the finished item.
I have attached a picture of the 25 100mmx100mm boards and a video of the table working. Each one had a SOIC PIC 18F26K22 on it, with 9 IR transmitters and receivers and 9 x WS2812b addressable LEDs on. They all kind of communicate with each other so that each board does the same IR reading of the same ‘pixel’ at the same time as the others. I simply have a pin on the board which outputs low whan it is working (taking a reading’, then after it is done, it changes to an input pin, it continually looks at this pin until it goes high, meaning all the other boards have also completed that particular reading and then it’s on to the next one.
I also have a calibration function so any thickness opaque covering can be put on the table top.
I have 2 buttons on it. One to change the colour (including the rainbow fade) and also a button to change the fade speed.
Thank you, Craig, for sharing your project! We’re glad you were able to get inspiration and helpful information from one of our projects.
Our friends at Mouser sent us this picture of their Octolively derived display, updated for the holidays:
We continue to have fun with your Octolively module design. In the attached photo you can see why we decided to use sockets for the LEDs on our boards. We plan on changing out the display for each of the holidays.
I was a little concerned at first about using the red LEDs with resistors that were chosen for white or blue, but they’re socketed, so replacing any that get damaged by overdriving should be easy! Looks like a fun way to celebrate at the office, and the snowflake tree-topper is a nice touch.
Mouser staff had been inspired by an installation of our Interactive LED Panels to create something interactive that they could show off at Engineers Week at the Fort Worth Museum of Science and History. They used the Octolively as the basis for their project, and the kids loved it of course.
For trade shows, they built up a display with a mix of blue and white LEDs to show off the Mouser “M”. Based on the foot traffic it got while I was at the booth, it is quite popular.
They made some minor changes from our original Octolively design and used different connector types to highlight Mouser’s product lines. The heart of the project is still the 40-pin DIP ATmega164P (perhaps anomalous at an ARM conference) running our Octolively code, which gave the Mouser folks a chance to play with some microcontroller programming.
It’s always exciting to see a derivative of one of our projects in the wild. Thanks to the Mouser folks for sharing their project story and sending the museum picture for us to share.
Four blue LEDs blink in sequence, powered by a CR1220 battery. The board is traditional OSHPark purple, with an ISP header for convenient reprogramming. They’re lighter than they look and quite comfortable.
Thank you, Rick! I know what I’ll be wearing to Maker Faire!
I bought the project to help expose my two grandsons to electronics and learn how to build circuit boards. Dan my 10 year old did one board all by himself just using your instructions. Josh my 14 year old did more than half of the boards and I finished them up because I only have the kids for limited time periods. I am so proud of them. Josh complete understands how the Game Of Life works…I don’t HA! We are planning on adding a instruction board to the bottom of the display so other kids can have fun.
I have a CNC router and built the frame. The boards are screwed onto a piece of 1/4″ plywood which floats in the frame. Not glue in. I machined a loose slot around the inside frame pieces. That way I can take the frame apart and easily change out of a board if necessary. It has been so much fun to build and you have SUPER service.
We thank you so much and would like to build more projects that you may come up with. As soon as I get more time with Dan we are going to build the clock.
He also shared his case design (105 kb dxf). Thank you for sharing your time and skills with your grandkids, and for sharing your pictures and design with the rest of us!
I wanted to say thank you for writing your blog and the products you’ve created. I used both to make my christmas lights this year. Couldn’t have done it without you.
I used an ATmega xx8 mini dev kit programmed with an ISP shield to control a series of WS2811 LED pixels to make beautiful light. The controller is designed to be standalone, not part of a bigger system. I used a BCD thumbwheel switch to select up to 10 looks.
We can give credit to the FastLED Library team for the heavy lifting. The case is from your friends at Adafruit. The target boards don’t quite fit in the Adafruit cases. Thankfully ya’ll had the schematic PDFs posted and I saw I could literally cut corners to make them fit.
Back to why I appreciate what you do so much, growing up my dad tried to teach me about electronics. He was putting motorola 6802 CPU’s in Sperry New Holland hay bale wagons. Unlike how easy we have it today with Arduino he had to program in assembly…
I got a degree in Theatre and loved doing sound and lighting design. So I really love the art you put into your technology. I’ve built many of your kits. My favorite are the interactive LED panels. Blinking lights! I like to put them behind the ikea glass “white boards” so my ideas really shine when I write them down. I’m looking forward to seeing what you do in 2015!
